Abstract

The invention relates to a telescopic single-container hanger using a servo motor. The hanger comprises an expansion and movement mechanism and a rotary pin mechanism, wherein the expansion and movement mechanism contains a first servo motor, a first reducer, a driving chain wheel, a chain, a driven chain wheel, a connecting plate and a push rod; the driving chain wheel and the driven chain wheel are separately arranged on the two sides of an annular chain wheel; the connecting plate is connected with the push rod and the chain; the push rod is connected with the end beam of the hanger; the rotary pin mechanism contains a second servo motor, a second reducer, a lower rotary arm, two connecting rods, a rotary pin component and a rotary handle; the lower rotary arm is connected with one end of each connecting rod; the other end of each connecting rod is connected with the rotary handle, and the other end of the rotary handle is connected with the rotary pin component. By using the hanger of the invention, many problems caused by the hydraulic system can be solved.

Description

technical field [0001] The invention relates to a container spreader, in particular to a telescopic single container spreader. Background technique [0002] At present, the telescopic single-container spreader used in container cranes is driven by hydraulic cylinders, which has many defects: [0003] 1. Due to changes in cylinder speed or leakage, its telescopic position is not accurate enough; [0004] 2. There is leakage in the hydraulic system, and there are many faults in use; [0005] 3. The existence of the hydraulic system makes the weight of the spreader heavier, and the occurrence of leakage makes the spreader less environmentally friendly. Contents of the invention [0006] The technical problem to be solved by the present invention is to provide a telescopic single-container spreader, which uses a servo motor as a driving force. [0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to propose a tel...
